Risk Analysis of Marine Riser Based on Improved Fuzzy AHP Method

Abstract:

Abstract: Many marine riser risk factors in service were analyzed and the riser risk factor hierarchical structure was modeled, the weight of each riser risk factor was evaluated by the improved fuzzy analytic hierarchy process (AHP) method. The simulation results and accident statistics from both home and abroad are in good agreement. It proves that the method has good practicability, more scientific, reasonable and simple than the traditional fuzzy AHP. The results provide theoretical reference for maintenance and management, danger elimination and reinforcement of marine riser.
